15: A run-on sentence is made up of two sentences that are joined without end punctuation or with just a comma.
16: I knocked on the door it opened.
17: It started raining, we ran inside.
18: To fix a run-on sentence, separate it into two sentences.
19: Add end punctuation after the first sentence, and capitalize the second sentence.
20: I knocked on the door.
21: It opened.
22: It started raining.
23: We ran inside.
24: You can also fix a run-on sentence by rewriting it as a compound sentence.
25: A compound sentence is two sentences joined by a comma and a conjunction such as and, but, or, or so.
26: I knocked on the door, and it opened.
27: It started raining, so we ran inside.

question: In this experiment, which were part of a control group?

choice: (A) the snowboards with wax removed (B) the snowboards with wax added

context: The passage below describes an experiment. Jeanette and Bryant were taking a snowboarding class. During the class, their instructor said they would go faster if they applied wax to the undersides of their snowboards. After the class, Jeanette applied a thin layer of wax to the underside of a snowboard and rode the board straight down a hill. Then, she removed the wax and rode the snowboard straight down the hill again. Bryant timed how long each ride took. Jeanette repeated these rides on four other snowboards, alternating whether she first rode with or without wax. Figure: a snowboarder.

gold answer: A

wrong prediction:

Rationale:

0: Experiments have variables, or parts that change.
1: You can design an experiment to investigate whether changing a variable between different groups has a specific outcome.
2: For example, imagine you want to find out whether adding fertilizer to soil affects the height of pea plants.
3: You could investigate this question with the following experiment: You grow one group of pea plants in soil with fertilizer and measure the height of the plants.
4: This group shows you what happens when fertilizer is added to soil.
5: Since fertilizer is the variable whose effect you are investigating, this group is an experimental group.
6: You grow another group of pea plants in soil without fertilizer and measure the height of the plants.
7: Since this group shows you what happens when fertilizer is not added to the soil, it is a control group.
8: By comparing the results from the experimental group to the results from the control group, you can conclude whether adding fertilizer to the soil affects pea plant height.
9: In this experiment, Jeanette and Bryant investigated whether applying wax to snowboards affects how fast snowboarders go.
10: The snowboards with wax added were not timed to go down the hill.
11: So, they were part of a control group.
12: The answer is B.

2: The unit shows what the number means.
3: When you are using customary units, length may be written with units of inches, feet, yards, or miles.
4: There are 12 inches in 1 foot, and 3 feet in 1 yard.
5: There are 5,280 feet in 1 mile.
6: A football is about 1 foot long.
7: A football field is 100 yards long.
8: The best estimate for the length of a sofa is 4 yards.

question: Which property do these four objects have in common?

choice: (A) rough (B) flexible (C) opaque

context: Select the best answer.

gold answer: C

wrong prediction:

Rationale:

0: An object has different properties.
1: A property of an object can tell you how it looks, feels, tastes, or smells.
2: Properties can also tell you how an object will behave when something happens to it.
3: Different objects can have properties in common.
4: You can use these properties to put objects into groups.
5: Grouping objects by their properties is called classification.
6: Look at each object.
7: For each object, decide if it has that property.
8: A flexible object can be folded or bent without breaking easily.
9: All four objects are flexible.
10: An opaque object does not let light through.
11: The hair clip is opaque, but the building blocks are not.
12: A rough object feels scratchy when you touch it.
13: The building blocks are rough, but the hair clip is not.
14: The property that all four objects have in common is flexible.
15: The answer is B.

question: Which word would you find on a dictionary page with the following guide words? beaver - bury

choice: (A) banner (B) brier

gold answer: B

wrong prediction:

Rationale:

0: Guide words appear on each page of a dictionary.
1: They tell you the first word and last word on the page.
2: The other words on the page come between the guide words in alphabetical order.
3: To put words in alphabetical order, put them in order by their first letters.
4: If the first letters are the same, look at the second letters.
5: If the second letters are the same, look at the third letters, and so on.
6: Put the words in alphabetical order.
7: Since banner is between the guide words beaver - bury, it would be found on that page.
8: The answer is A.

question: Think about the magnetic force between the magnets in each pair. Which of the following statements is true?

choice: (A) The magnitude of the magnetic force is the same in both pairs. (B) The magnitude of the magnetic force is greater in Pair 2. (C) The magnitude of the magnetic force is greater in Pair 1.

context: The images below show two pairs of magnets. The magnets in different pairs do not affect each other. All the magnets shown are made of the same material, but some of them are different shapes.

gold answer: B

wrong prediction:

Rationale:

0: Magnets can pull or push on each other without touching.
1: When magnets attract, they pull together.
2: When magnets repel, they push apart.
3: These pulls and pushes between magnets are called magnetic forces.
4: The strength of a force is called its magnitude.
5: The greater the magnitude of the magnetic force between two magnets, the more strongly the magnets attract or repel each other.
6: You can change the magnitude of a magnetic force between two magnets by changing the distance between them.
7: The magnitude of the magnetic force is greater when there is a smaller distance between the magnets.
8: Distance affects the magnitude of the magnetic force.
9: When there is a smaller distance between magnets, the magnitude of the magnetic force between them is greater.
10: There is a smaller distance between the magnets in Pair 1 than in Pair 2.
11: So, the magnitude of the magnetic force is greater in Pair 1 than in Pair 2.
12: The answer is C.

1: They tell you the first word and last word on the page.
2: The other words on the page come between the guide words in alphabetical order.
3: To put words in alphabetical order, put them in order by their first letters.
4: If the first letters are the same, look at the second letters.
5: If the second letters are the same, look at the third letters, and so on.
6: If one word is shorter, and there are no more letters to compare, then the shorter word comes first in alphabetical order.
7: For example, be comes before bed.
8: Put the words in alphabetical order.
9: Since clutch is between the guide words criticism - cultivate, it would be found on that page.
10: The answer is A.

question: Which of the following contains a vague pronoun reference?

choice: (A) I didn't like the ending of The Fault in Our Stars, but the book critic thought it was well-written. (B) The book critic thought The Fault in Our Stars was well-written, but I didn't like the ending.

gold answer: A

wrong prediction:

Rationale:

0: When writing, make sure to avoid vague pronoun references.
1: A vague pronoun reference occurs when a pronoun could refer to more than one possible antecedent.
2: When Lisa and Kim finally landed, she breathed a sigh of relief.
3: The pronoun she could refer to either Lisa or Kim, so the meaning of the sentence is unclear.
4: Vague pronoun references can be corrected in one of two ways: 1.
5: Replace the pronoun with its correct antecedent: When Lisa and Kim finally landed, Lisa breathed a sigh of relief.
6: 2.
7: Rewrite the sentence: Lisa breathed a sigh of relief when she and Kim finally landed.
8: A vague pronoun reference also occurs when they, them, their, theirs, it, or its is used without its antecedent.
9: They say that this nail polish dries in less than five minutes.
10: The pronoun they is used without its antecedent, so the meaning of the sentence is unclear.
11: This problem can be fixed by replacing the pronoun with its missing antecedent.
12: The advertisements say that this nail polish dries in less than five minutes.
13: The first answer choice contains a vague pronoun reference.
14: The pronoun it could refer to the book critic or the ending of the book.
15: The book critic thought The Fault in Our Stars was well-written, but I didn't like the ending.
16: The second answer choice shows a possible correction for the vague pronoun reference.
17: The text has been rewritten so that the meaning is clear.
